[NSRCA-discussion] wing tube sleeve hole

[Lance Van Nostrand]

That's a hard one, Mike.  Both Terry and I use a similar method.  We had a machine shop make a jig for the cutter.  The cutter is a length of 7/8" wing tube with  a ground sharp edge, but the jig to hold it has got to be made presicely.  I used to use a seemingly accurate jig made to the plans provided in a KFactor several years ago, but my results were not good enough.

  Terry Brox's web site on balsa skinned wings is very good and does show the drilling of the servo lead hole with a tube and by hand. 

  Their is some great information on these sites on building foam core wings. But a very important part of a plug in wing would be the wing tube sleeve hole in the core, to be straight and parallel to the desired line centered and at the right angle to set the dihedral. Is there a site that explains or shows the process of set up and drilling of this hole? If this step is not perfect looks to me like the wing is dead no matter how good the skinning process is.
  Thanks in advance

  Mike
